(The former could be worked around by calling the FBIOPUT_VSCREENINFO ioctl with having the FBACTIVIATE_FORCE flag set.) This patch automatically sets the line_length correctly, and the video mode is derived from the bit depth now as well. Thanks to Geert Uytterhoeven for confirming the bug and helping me with the patch.

This patch removes the second unnecessary memset in vfb_probe.

It contains generic video related files, directories for backlight, console, linux logo, lots of fbdev device drivers, fbdev framework files. Make some order into the chaos by creating drivers/video/fbdev directory, and move all fbdev related files there. No functionality is changed, although I guess it is possible that some subtle Makefile build order related issue could be created by this patch.
